Filter by Author6 report(s) found for Andrew Sorensen 1 - 6 of 6 Ultra-high-performance concrete (UHPC) is distinguished by its superior mechanical and durability properties. These characteristics are attained through a precise mixture design that includes a low water-to-cement ratio, high fineness supplementary cementitious materials (SCMs), and steel fibers. This... Recently, significant advances have been made in the development of rapid setting cementitious materials for partial-depth bridge deck repair. The rapid set times of these materials allow for traffic to be re-opened onto the bridge deck in several hours versus days once the material has been placed.... With the development of accelerated bridge construction (ABC), the seismic performance of typical ABC column-footing connections has been evaluated in high earthquake-prone states, like Utah, California, Nevada, and Idaho. But to date, the current literature has yet to fully examine the impact behavior... With the popularization of accelerated bridge construction (ABC), the utilization of splice sleeve connections has been researched to determine their performance using a variety of connection details and under several loading scenarios. However, fundamental research on the load distribution and load... Polymer concrete (PC) has found increasing use in construction over the last few decades. One common use of this material is as an overlay material on bridges and highways. This use can be attributed to some advantages of this material such as its high bond strength with substrate concrete, short curing... Calcium sulfoaluminate (CSA) cement was used to cast a prestressed voided deck slab bridge girder. The rapid-set properties of CSA cement allowed the initial concrete strength to reach the required 4300 psi needed in order to cut the prestressing strands 6.5 hours after casting. Prestress losses were... |
